  • Patent number: 7710342
    Abstract: A dual-port corporate-feed broadband antenna uses two pairs of crossed dipoles in each bay, fed by a single hybrid coupler in each bay, to support hybrid-mode IBOC® VHF-band broadcasting. Each 3 dB quarter-wave coupler receives a share of an analog FM broadcast signal on a first input and a digital OFDM broadcast signal, 20 dB down, on a second input. The respective coupler output ports drive coaxial lines to tees feeding respective quarter-wave-separated crossed dipoles. The dipoles in each bay are arranged in a square to one side of their coupler, making side mounting practical. The resultant omnidirectional analog and digital radiation patterns have the same circular polarization and opposite phase rotation. Bay spacing for vertical null is a function ((n?1)/n) of the number of bays in the antenna.

  • Publication number: 20100066625
    Abstract: An antenna assembly includes an antenna housing, an antenna located within the housing, a radio frequency (RF) module located within the housing and connected to the antenna, and a wire assembly operably associated with the module. The module includes a radio frequency device, such as a transmitter, receiver or transceiver, electrically connected to the antenna. The wire assembly includes electrical wires for providing external power to the module and conducting processed signals between the module and external circuitry. The proximal nature of the antenna and RF module reduces or eliminates induced power losses between the antenna and module, resulting in a very effective power transfer ratio. A conductive sleeve is located in the housing and surrounds the RF module. The conductive sleeve is electrically connected to the module to thereby provide a ground plane for the antenna and a shield against outside emissions.
